range of 'Disciplines' (RUP terminology) that are explicitly
addressed by the agile methodology in question. Thus
Scrum is perceived to be chiefly concerned with PM discipline,
AM is perceived to be concerned with A&D, FDD is
perceived to be concerned with Requirements, A&D, Code
I guess we all tend to think that *our* area of interest is the
one that really matters.

- While I agree with Mike in general, it is of interest that the first Scrum
was building an OOAD tool and we decided the team should eat their own
dogfood. It was also the first round trip engineering tool.
Every developer had the model of his components on his wall.
Our senior consultant, Jeff McKenna, an ace Smalltalker, would walk into a
cube and an hour later the model was in shreds on the floor. He had shown
the developer how to refactor the model and eliminate half the code while
enhancing performance and functionality.
I've never seen another team that can operate at that level.
